The existing OLIM/OBIM researches focus on finding a set of seed users (or billboards) under the current social network or trajectory databases. However, commercial companies want their product information to be disseminated to the majority of their customers over a period of time after they have spent their budget. Therefore, the seed users selected by using existing OLIM/OBIM methods may not have a good performance for influence spread in the following period, as the network topology often evolves in the real world [1]}.
